Last year, I wrote about\xa010 of the most interesting predictors of longevity. Many of them were subjective, but, as we all know, the objective physiological processes that occur in the human body also predict how long we live. Luckily, we can measure most of them. Some are standard at doctor\u2019s checkups. Some require more involved (and expensive) testing. Some you can complete yourself at home with simple household objects.

But if you care at all about how well you\u2019re doing in the longevity game, it\u2019s worth paying attention to some of them.
